Expanding support for Kworkflow: bootloaders and Linux distributions

Kworkflow is a kernel developer workflow tool with the simple mission of reducing the overhead with infrastructure setup for Linux development. In order to accomplish this goal, Kworkflow (or kw as it is commonly called by the community) must support a wide range of different setups. However, kw currently only supports two families of Linux distributions (Debian and Arch) and one bootloader(GRUB2). To help Kworkflow better accomplish its mission, the first half of this project will be dedicated to expanding support to some key bootloaders/bootmanager such as: U-boot (widely used by embedded systems and by ChromiumOS), rEFInd and the RaspberryPi bootloader. The second half of this project will build upon the work previously done by adding support to other Linux distributions, such as the RHET family and the ChromiumOS (through the newly supported U-boot).
